Abstract
Through analyzing the application status of Vehicle Ad Hoc NETwork(VANET) in road transportation field,according to the characteristics of VANET and challenges in news transmission process,concerning the problems of previous algorithms being difficult to establish spatial model accurately and hardly considering the regularity characteristics of social behavior,a routing scheme named HBSR was proposed based on the historical behavior statistics of vehicles,including nodes connected algorithm calculating the connectivity between vehicles,topological overlap algorithm calculating the number of periods between the source node and destination node,paths selected algorithm selecting messages forwarding paths and loss strategy.Compared with several typical routing algorithms on ONE simulation platform,the simulation results prove that HBSR can find news forwarding paths more effectively,and reduces message delivery delay obviously while delivery rate increases significantly,and performance is relatively stable in VANET.
